Unitree has a robot dog that moves at full speed across seemingly impossible terrain. Its trick: legs with wheels

Unitree unveiled the As2-W, a quadruped robot dog with wheeled legs designed for rough terrain.

The demo showed it climbing obstacles, handling steep slopes and rivers, and reaching speeds up to 6 m/s while carrying loads.

The video went viral on X and YouTube, with reactions ranging from hiking use cases to concerns about military applications.

The launch highlights rapid progress in extreme mobility for quadruped robots and renewed debate over civilian versus surveillance or defense uses.
